CIRCULATING-VALVE.

SPECIFICATION forming part of Letters Patent N 0. 659,050, dated October2, 1900. Application filed December 1, 1899. Seri l 73 19 N mo lin thevalve nor retard the flow of either of said currents of water norcommingle the cooled water with the hot in the valve, thus preventingthe return of some cooled water with the current of hot water throughthe radiator, and, further, to provide for continnous circulationthrough the pipes leading to and from the radiator when the valve isclosed, so that other radiators in the system may operate unimpaired byone that is temporarily cut out.

My object is further to provide for aslight continuous flow through vtheradiator when the valve is closed to thereby supply sufficient heat tothe radiator to prevent freezing.

My invention consists in certain details in the construction,arrangement, and combination of the various parts of the valve, ashereinafter more fully setforth, pointed out in my claims, andillustrated in the accompanying drawings, in which- Figure 1 shows thecomplete valve-casing,-

valve, and coupling in longitudinal section. Fig. 2 shows in perspectivethe valve detached, and Fig. 3 is a horizontal sectional view taken on aline above the disk of the valve.

Referring to the accompanying drawings, I have used thereference-numeral 10 to indicate the valve-casing. At one end of thecasing is the induction-opening 11 and the eductionopening 12, bothleading to the chamber for containing the valve, which is located inabout the central portion of the valve-casing.

In this valve-chamber the valve proper 'is located. This valve comprisesa semicircular portion 13, having near its central portion an integralvdisk 14 of a size to exactly passage-way l9.

fit the interior of the valve-chamber. Above the disk 14 is asemicircular cross-piece 15, to which the valve-stem (indicated by thenumeral 16) is detachahly connected, and at or near the central portionof the part 13 is a small opening 17 above the disk 14 and a similaropening 18 below the disk 14 for purposes hereinafter made plain. In thepartition between the induction and eduction openings 11 and 12 I haveprovided a small At the end of the valvechamber opposite from theinduction and eduction openings is a tubular extension 20, having abeveled ground surface at 21 and a screw-thread on its exterior, and aslight distance below its central portion is an integral horizontalpartition 22, arranged in position substantially in alinement with thedisk 14.

The coupling of the pipe (indicated by the numeral 23) is provided witha ground-surface at 24 to mate with the ground-surface 21, and thesliding collar 24 of this coupling is screw-threaded on its interior tocoact with the screw-thread on the exterior of the extension 20. On theinterior coupling 23 is a horizontal partition 25, formed integrallytherewith and extending a considerable distance beyond the coupling.Said partition is designed when the coupling is securely at tached tothe extension on the valve-chainber to assume a position in aliuementwith the partition 22.

In practical use, and assuming that inflow and outflow pipes wereconnected with the passage-ways 11 and 12 and that the coupling 23 wasscrewed into a radiator, it is obvious that when the valve is opened thehot water will flow through the valve-chamber and into the radiatorabove the disk 14, partit-ion 22, and the partition 25, and then, afterpassing through the radiator and becoming somewhat cooled, it is obviousthat the return Water from the bottom of the radiator will flow backbelow the said partitions and disk through the opening 12; and obviouslythese two currents of water will not be commingled nor the flow of hotwater to the radiators be impeded by friction with the returning flow ofcold water, and, further, assuming that the valve was closed, it isobvious that a slight circulation of water through the pipes in thesystem may be maintained through the opening 19. It will also be seenthat by reason of the openings 17 and 18 in the valve a slight flow ofwater will be maintained at all times through the radiator, thuspreventing the water in the radiator from freezing without to any greatextent heating the radiator. It is also obvious that when connecting mydevice with a radiator the partitions 22 and 25 may readily be made toaline, because the coupling-pipe 23 is first screwed into theradiator,aud it is turned farenough to bring the partition 25 to ahorizontal position. Then, as the valve-chamber tnust necessarily extendin such a position that the partition 22 therein will extend in ahorizontal plane, these partitions must necessarily be in such positionsas to form continuous passage-ways above and below them.

Having thus described my invention, what I claim, and desire to secureby Letters Patent of the United States therefor, is-

1 The combination, with a valve-chamber having induction and eductionopenings at one end, arranged the one above the other, and a tubularextension at the other end, of a semicircular valve in thevalve-chamber, a disk-shaped partition secured to the semicircularvalve, a valve-stem connected with the valve, and a partition in thetubular extension,arrangedsttbstantiallyinalinementwith the saiddisk-shaped partition, for the purposes stated.

2. The combination with a valve-chamber having induction and eductionopenings at one end, arranged the one above the other, and also havingpassage-ways between said openings, and a tubular extension at the otherend, of a semicircular valve or Valvechamber, a disk-shaped partitionsecured to the semicircular valve, a valve stem connected with the valveand a partition in the tubular extension, arranged substantially inalinement with the said partition for the purposes stated.

3. The combination, with a valve-casing having induction and eductionopenings at one end and a tubular extension at the other end, of asemicircular valve in the casing, a disk shaped partition connected withthe valve, a horizontal partition in the said tubular extension, and acoupling-pipe designed to be connected with said tubular extension and ahorizontal partition in said couplingpipe to project beyond it anddesigned to aline with the partition in the tubular ext-ension, for thepurposes stated.

4. The combination with a valvecasing having induction and eductionopenings at one end and a tttbular extension at the other end, of asemicircular valve in the casing, a disk shaped partition connected withsaid valve, said valve being provided with a passage-way above and apassage-way below the said disk-shaped partition, for the purposesstated.

5. An improved circulating-valve, comprising in combination a casing,induction and educt-ion pipes admitted into one end of the casing theone above the other, a horizontal partition in the casing to separatethe induction and eduction pipes, a tubular extension at the oppositeend of the casing, a horizontal partition in said tubular extension, anda valve located between the said partitions and arranged to be capableof cutting off the flow above and below said partitions when closed, andfor permitting the flow above and below said partitions when open, and apartition connected with the valve for cutting off communication betweenthe upper and lower chambers when the valve is either open or closed,substantially as, and for the purposes stated.

6. The combination with a valve-casing having at one end induction andeduction openings, and at the other end a tubular extension, of ahorizontal partition in the said tubular extension, a valve in thecasing, and a partition connected with said valve, said partition beingdesigned to aline with the aforesaid partition when the valve is open toform continuous passageways through the valve-chamber above and belowthe said partitions, for the purposes stated.
